Hardcore cypherpunks will probably find the cryptographic modules
written by A.M. Kuchling of further interest; the package adds
built-in modules for DES and IDEA encryption, provides a Python module
for reading and decrypting PGP files, and then some. These modules
are not distributed with Python but available separately. See the URL
http://www.amk.ca/python/code/crypto.html
for more information.
